Unlocked Grotto is opened – Enter and defeat Eldritch Guardian, he will then drop the fourth shard.

Eldritch Symbols V

Prelude: Complete The Glenmire Staff line of quests. For me this line began at level 16. It begins with Storm the Castle and ends with Shores of the Lost City, level 19.

Prelude: After turning in the quest, Shores of the Lost City you will receive a quest called The Golem. He is located in Lake Nithus, in the center where the cave used to be. After defeating him, he will drop the Nithus Treasure Map.

This will open the Underwater Grotto. Enter and receive last Eldritch quest.

Turn in Golem quest to Daedalus and receive quest Defeat Lord Helion. Head back to Lake Nithus.

IMPORTANT NOTE: When turning in The Golem quest, you will receive a quest to Defeat Lord Helion. Do Not do this quest until you receive Eldritch Symbols V quest from the Grotto – items needed for Eldritch will be dropped in Lord Helion’s Temple (dungeon).
